Are Malcolm and Tristan still together at the end of the reboot?

During the final episode of the reboot, Malcolm proposes to Tristan during his parents’ anniversary party. Her response? “No! Malcolm, I love you so much. But we both just found out we’ve been keeping gigantic, awful secrets from each other. We have to figure that out before we do anything… Except sex, we’ll definitely have sex later.” After all that, it’s clear Malcolm and Tristan are endgame, at least for now, even if they’re not tying the knot anytime soon.

Who is the mother of Malcolm’s daughter?

In the reboot, Malcolm reveals that he has a daughter named Leah. Explaining how he became a single father, he joked, “She’s kind of a trophy I won in college for attending my first kegger.”

According to Malcolm, Leah’s mother left them three days after giving birth and has not returned since. “Her mother, Dreamer, yes, her name is Dreamer, ran off three days after giving birth so… Single father,” he revealed.

Who plays the mother of Malcolm’s daughter?

In the only photo of Dreamer shown, she sits in a hospital bed with a beer in one hand and a cigarette (and baby Leah) in the other. There she appears to have a Cruella de Vil-style black and white mullet with micro bangs, matching her deeply smudged black eye makeup. Currently, the actress playing Dreamer in the photo is not credited.
